At the UN Pope Francis held up Thomas Merton as an example.
Here is a bit of Thomas Merton, the example:
Pope Francis quoted Thomas Merton. Here is Merton on chant:
This is what I think about the Latin and the chant: They are masterpieces, which offer us an irreplaceable monastic and Christian experience. They have a force, an energy, a depth without equal. All the proposed English offices are very much impoverished in comparison — besides, it is not at all impossible to make such things understood and appreciated. Generally I succeed quite well in this, in the novitiate, with some exceptions, naturally, who did not understand well. But I must add something more serious. As you know, I have many friends in the world who are artists, poets, authors, editors, etc. Now they are well able to appreciate our chant and even our Latin. But they are all, without exception, scandalized and grieved when I tell them that probably this Office, this Mass will no longer be here in ten years. And that is the worst. The monks cannot understand this treasure they possess, and they throw it out to look for something else, when seculars, who for the most part are not even Christians, are able to love this incomparable art.&
— Thomas Merton, in a letter to Dom Ignace Gillet, Abbot General of the Cistercians of the Strict Observance (1964)
